Specification of Letters Patent.

Patented March 12, 1907,

Application filed November 15, 1905. I Serial No. 287,517.

To all whom it may concern:

Be it known that I, WILLIAM W. GREEN, a citizen'of the United States of America, residing at Niles, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Blowers, of which the followin is a specification.

My invention relates to improvements in blowers, and is fully described and explained in this specification and shownin the accompanying drawings, in which Figure '1 is alongitudinal section through my improved device in the line 1 1 of Fig. 4. Fig. 2 is an elevation of the drum. Fig. 3 is an elevation of one of the packing-rollers. Fi 4 is a transverse section in the line 4 4 of 5 is a section in the line 5 5 of Fig. 1. Fig. is a section in the line 6 6 of Fig. 1 looking the direction of the arrow, and Fig. 7 is an elevation of the right hand end of the drum as viewed in Fig. 1.

-Referring to the drawings, A is acentral hollow cylinder having upwardly-projecting bosses a a, which operate as inlet and exhaust ports, respectively, in the ordinary operation of the machine. It will he understood that the machine may be run in either direction and the function of these ports reversed, but in the operation as herein de scribed the boss a will be assumed to be an inlet and the boss a the exhaust port. End

, plates A A are secured to opposite ends of the cylinder A to inclose the same, and these end plates are shaped, as illustrated in the drawings and as will be hereinafter set forth, to receive certain of. the moving parts. l/Vithin the cylinder A is a cylindrical drum B, said drum comprising a central portion 6, longitudinally slotted from end to end, an end plate I), secured to the left hand end of the central portion 6, and an end plate I),

referably integral with the central portion h The end plate 6 runs within the end piece A of the cylinder and is provided with a hollow projecting sleeve 6?, which runs in -a projecting boss (1 on the end piece A I The projecting sleeve 5 has at its end a drivforthe purpose in the end piece ing-pulley C, by which the drum B can be rotated. The end piece I) of the drum'B is provided with a sleeve 5 shorter than the sleeve 5 and of larger diameter, and this sleeve runs in a cylindrical space rovided of the aimcylinder, antifi'iction-rollers 6 being interposed between the said sleeve and the adjacent surface of the and piece. By the means thus described the drum B is given a firm rotative bearing in each end of the cylinder, on which bearings it can readily be rotated. It will be observed that as the drum is rotated it remains constantly in odd tact with the upper element of the cylinder A between the ports a and a, as seen in Fig. 4.

The end piece A is provided Witha projecting boss a centrally disposed with respect to the cylinder A, and this boss supports a shaft D, which is locked against rotation by means of a nut d. The opposite end of the shaft D is supported in a cylindrical block E, mounted in a cylindrical hollow provided for the purpose in the end of the drum B. This block is nOn-rotatably secured to the end'of a shaft F, which runs through the center of the sleeve 6 and is non-rotatably supported at its free end by a bracket The block E is locked upon the shaft F by a set-screw 2. By this arrange ment the shaft D is given a firm and substantial bearing at both ends and the sleeve 6 is given an internal stationary bearing.

It will be seen that the end plate b of the drum is perforated to receive the ends of three packing-rollers G, which lie in line with the slots in the centralportion b of said drum.

The o posite ends of the packing-rollers are passer. through corresponding perforations in an inwardly-projecting flange which is formed on the centralportion b of the drum, and longitudinal movement of the packing; rollers is prevented by the end plate I) on the drum. These rollers are longitudinally slotted and fit tightly upon piston-vanes H, which are pivotally secured to the shaft 1), as illustrated. These piston-vanes are of such length that each extends through the pack- 9 ing-roller and the wall of the drum to the inner surface of the cylinder A.

' The operation ofniy device is readily apparent. When power is a plied to the pulley C, the drum B is-rotate and this rotation causes constant rotary, movement of the iston-vanes about the stationary-shaft D. ach of the vanes as it passes the inlet-port sucks in fluid behind i: the fluid so sucked in being pushed forward by the next succeeding vanes and finally forced from-the exhaust ort. The drum B cuts off'communication etween the two ports and causes thefluid to flow from the e aust-port rather than in a circle about the blower.
